Job Description

Pacific Northwest National Laboratory (PNNL) is recruiting an early career scientist interested in developing new scientific insights into the initiation, organization, dynamics, and microphysics of convective cloud populations. You will be expected to work as part of a team of scientists investigating convective clouds, with a long-term goal of using new observational, theoretical and modeling insights to improve representation of convection and microphysical processes in both high resolution regional and global models. Specifically, you will be expected to apply modern statistical and computational methods to analyze large data-sets from observations (e.g. radar, satellite) and models (LES, regional-scale, global climate) to understand cloud-environment interactions that lead to convective transitions. Two-way interactions of microphysical processes with convective circulations such as updrafts, downdrafts, and cold pools on fine spatiotemporal scales are of particular interest. The ability of multi-scale models and variable complexity physics parameterizations to capture observed cloud and environmental processes will be critical in predicting the convective life cycle. You will identify sources of model biases through innovative model sensitivity experiments design and evaluation.

An ability to analyze large observational (e.g. radar, satellite) and model (LES, regional-scale, global climate) datasets and to pose hypotheses that tease out new insights from the large datasets is critical. Using data assimilation techniques to constrain environmental conditions in models and better represent cloud distributions is desirable. In collaboration with others on the team, you may also contribute to analyzing the ability of models to reproduce the observed impacts of convective clouds and precipitation on surface properties, aerosol redistribution, and boundary layer evolution with feedbacks to subsequent convective cloud development.
